Noun.
A sexual act which involves pressing the nose into the Vagina, the toungue into the anus, and humming. Generally used as the finishing move in a session of cunnilingus.
Not all women respond to this, but those who do respond in a big way.
Also known as the "lady's hummer".

NOTE: Please take extreme care not to exhale through the nose into the vagina. This is physically dangerous to both partners. Breathe through the mouth, and never, in any sexual act, blow into the vagina or penis!

It may have a racist name, but the ladies love it. Are you man enough to play the Jew's Harp?
